FLUSI-IING APPARATUS.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed January 2, 1917, Serial No. 140,038. Renewed April 7, 1919. Serial No. 288,405.

To all whom it may concern:

Be it known that I, Louis MEYER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Flushing Apparatus, of which the following is a specification.

The object of the present invention is to provide a flushing apparatus which will be compact in form, which will not depend upon the use of floats for filling the tank, which will be practically noiseless in operation, which cannot get out of order, and which can be easily operated.

In the accompanying drawing, Figure 1 is a vertical sectional View of my improved flushing apparatus, certain parts being shown in side elevation, said apparatus being shown in the condition in which a stand pipe has just been filled with water and a lower buoyant valve has not yet been lifted from its seat by the equalization of the pressure of the water below it to that above it; Fig. 2 is a cross sect-ion on an enlarged scale on the line 22 of Fig. 1; Fig. 3 is a cross section on the line 33 of Fig. 2; Fig. 4 is a cross section on the line 44 of Fig. 1; Fig. 5 is a sectional view of a modified form of tank; Fig. 6 is a view similar to Fig. 1, but showing the parts in a difierent position; Fig. 7 is a view similar to Fig. 2, showing the parts in same position as in Fi 6.

Feferring to the drawing, 1 indicates a casting forming a valve casing, having at one end a depending tubular portion 2, internally threaded to be connected with a vertical pipe for supplying water under pressure, having also, near the other end, a depending tubular portion 3 forming a discharge conduit and leading to the bowl to be flushed, and having also, at said latter end, an upwardly extending curved passage 4 formed at the top with a valve seat 6, said casting at said end above said valve seat forming a hemispherical chamber 7 to receive a hollow ball valve 8 on said seat. The upper end 9 of the casting, in which is said hemispherical portion, is externally threaded I to be screwed into the lower end of a stand pipe or tank 10, having'at the upper end a valve seat 11, against which a hollow ball 12 floating on the water in said tank, is seate by the pressure of said water, said seat being interposed between said tank and an air chamber 13 communicating by an air outlet pipe 14 with a conduit 15 cored in the casting of the valve casing, and communicating with the discharge passage 3.

The end of the valve casing remote from the cap extension is enlarged or flanged to form the inner side of said annular chamber 18, and presses a washer 22 against a circular shoulder 23 formed in said casting 1.

A lower rear portion of said annular chamber communicates by a curved passage 24- with a release chamber 25 which communioates at the bottom with the depending portion 2. The communication between the curved passage 24 and the release chamber 25 is adapted to be closed by a controlling valve 26. Said valve comprises a main body 27, into one end of which is screwed a screw 28, around the stem of which are two rubber washers 29 with an intervening metal ring 31. Intov the other end of said body 27 is screwed a screw 32 around the stem of which are secured two cup leathers 33, 34, an intervening metal ring 35 and an outer metal ring 36. Said body is in the form of a cylinder having portions of its round side cut away or flattened, as shown at 37, and said cylinder slides in a valve casing 38, screwed, as shown at 39, into a laterally directed internally apertured and threaded extension 40 of the casting 1, a gasket 41 being interposed between said extension and a shoulder 42 of the valve casing 38.

The slide valve is longitudinally moved in said valve casing by means of a handle 44, secured to a stem 45, which carries at its inner end a cylindrical enlargement 46 formed with two diametrically opposite cam-like recesses 47 which engage cam-like projections 48 from a collar 49 loosely surrounding said stem, and screwed, as shown at 50, into the outer end of the valve casing 38. When said stem is turned through a small angle the walls of the cam-like recesses 47 engage the walls of the cam-like projections 48 and cause said stem to move inwardly. Thereby the enlargement '46, caused to press against a ring 51 surrounding the head of the screw 32 and abutting against the outer ring 36 on the screw 32, so that said valve 26 is pressed inwardly against aseat 52 formed around the entrance of the curved passage 24 into the chamber 25, thereby closing said entrance. At the same time, water from the source of supply, passing into said chamber 25, can pass around the cut-away portions 37 of the main body of the valve, andthrough holes 53 in the valvecasing 38 terminating in a groove 54 around'said valve casing, which communicates with a conduit 55 formed in the casting 1. -Said conduit leads to an annular chamber 56 formed by said casting 1 and a slide valve 57 having a circumferential flange 58, abutting against one side of which flange is a cup leather 59 pressed against said flange by a brass ring 6O screwed on said valve. 'Said valve is hollow and is provided at one end with a cup leather 61 se cured-in-place'by aflanged tube 62, threaded on the outside and screwed into the threaded inner surface of said end of the valve 57. At the other end said valve is closed, and a leather disk 63 is secured on said end by nieansof a screw 64, which screw has therethrough a small central aperture 65. Said disk is adapted to be pressed against a seat to close saidpass'age 4. From the annular-space between the flange 58 and the inner cnd of the extension 21 oft-the cap'there extends a conduit'66 cored in the casting 1, and discharging intothe discharge passage 3. The chamber '56 also communicates by a small passage 67 with saiddisch-argepassage 3. An air'outl'et 68 is provided from the curvedpassage '4.

In the form of the invention shown in Fig. 5, the air chamber 13, the'pipe'14 and the c0redportion 15 of the apparatus are dispensed with, and the top of the pipe or tank 10 is closed by a screw cap 77. Theair entrapped inthe tank is compressed therein by thepressure of the water, and the water is discharged from said tank under said pressure.

TdfllLthe'pipe'or tank after installtio'n,

theservice valve from the main is opened. Water then enters through the" passage 2 and flows'into the chamber 25 and past the end of the control yalve through the passage 6 into'the annular chamber 18. It then flows by the conduit 19 into'the stand pipe or ta'nk. As it fiows'i'nto said tank its weight holds the ball 8 down to 'itsseat 6 and prevents the waterfrom flowing downward through v said. seat into the passage 4, which it could otherwise do, since at this time the valve 57 has not yet been closed 'a'gainst said seat. In this way the stand pipe is filled with flows through the circular series of holes 30' into the interior of the hollow valve .57, pressing said valve to its seat 70. At the same time water is allowed to-escape from the annular chamber 56 through the small hole 67 leading from said chamber into the passage 3. By maln'ng this hole small the closing of the valve 57 takes place slowly, and without violence or noise. Water then flows through the aperture65 until thepassage 4 is filled with water of the same-pressure as in the stand pipe, whereupon the ball valve 8 rises by its buoyancy. p

The device is now ready for operation.

To operate it the handle 44is turned through a small angle. Thereupon the valve27 is moved lnwardly against the seat 52, closing the passage of water to the stand-pipe anl The pressure water entering said annular chamber forces the valve 57 backward and allows water from'the stand pipe'toflowby the passages 4 and 3, air orwaten'if-there should be any leakage, escaping from-Qthe rear of the flange 58 byjthe conduit-66, which discharges into the passage 3. When the valve 57 has beenforced back 'toits'furthest position, the pressure inthe annular chamber 37 rises to normal city pressure, and said pressure, being transmitted through the passage 55, groove 54 and holes 53 into the chamber 25 forces the control valve backward and returns the handle to its original position, thereby closing the communication between the chamber 25 and the holes 5'3 and opening the passage 24 to refllltlie stand pipe. Water-then'flows into the stand pipe in the mannerfirst described.-
